[ipxe-devel] iPXE + UEFI + WINPE5 Failures on HP Z230 Workstations

[Jessica Hamilton]

Hi,

I'm having real problems trying to make any headway trying to boot a
WINPE5 based ISO image with iPXE.

My iPXE script currently looks like the following:

kernel /iPXE/wimboot
initrd /Images/Autoghost4.02/contents/BOOT/BCD BCD
initrd /Images/Autoghost4.02/contents/BOOT/BOOT.SDI
initrd /Images/Autoghost4.02/contents/SOURCES/BOOT/Windows/Boot/EFI/bootmgfw.efi
bootmgfw.efi
initrd /Images/Autoghost4.02/contents/SOURCES/BOOT.WIM
boot

But it's failing to load the EFI loader with the error EFI_UNSUPPORTED.

Output is as follows:
Using bootmgfw.efi via 0xbb037588 len 0x14a560
...found bootmgfw.efi file bootmgfw.efi
Using BOOT.WIM via 0xbb037628 len 0xb8e75e1
...found WIM file BOOT.WIM
Using wimboot via 0xbb0376c8 len 0x8440
Read bootmgfw.efi
Could not load bootmgfw.efi: 0x8000000000000003
Could not boot: Error 0x7f048281 (http://ipxe.org/7f048281)

I've also tried adding initrd line for bootmgr.efi as well, after
first attempt at "boot", it fails as before, but a second attempt at
"boot", I get the following:

Could not install disk block I/O protocols: 0x8000000000000014, which
I believe maps to EFI_ALREADY_STARTED?

I'm really very stuck at this point :(
